WebSep 6, 2024 · The set of natural numbers is represented by the symbol N. N = {1, 2, 3, 4, 5, … ∞}. One (1) is the lowest natural number. A collection of elements is referred to as a set (numbers in this context). The smallest element in N is 1, and the next element in terms of 1 and N for any element in N. 2 is 1 greater than 1, 3 is 1 greater than 2, and so on. WebSep 12, 2024 · Method 2 :- The idea is the sum of first n even number is n (n+1), for find the Average of first n even numbers divide by n, hence formula is n (n + 1) / n = ( n + 1). i.e. Average of first n even numbers is n+1. it take 0 (1) time. Avg of sum of N even natural number = (N + 1) Proof china bar box hill
